Rodolphe III of Gruyère

Rodolphe III, called the Younger (c. 1200–1269/1270), was count of Gruyère and the eldest son of Rodolphe II and Gertrude of Montagny. He had to surrender the estate of Ogens, his wife Colombe of Belmont's dower land, to William of Ecublens, bishop of Lausanne.

On 19 April 1244, under pressure from Count Peter II of Savoy, he yielded Gruyères Castle as freehold; the fief was regranted to his son William. His son Peter II succeeded him.
